The table below shows data for stuffed animals sold at a zoo gift shop. If the data were represented with a comparative dot plot, which animal would have more dots for month 2 than month 1
Answer:elephant
Step-by-step explanation:
23x18
Elephant would have more dots for month 2 than month 1. The Option C.
Which animal has more dots in month 2?Comparing the data for stuffed animals sold at a zoo gift shop in month 1 and month 2 using a comparative dot plot, it is evident that the elephant has a higher number of dots in month 2.
This indicates that more elephant stuffed animals were sold in the second month compared to the first month. The dot plot allows us to visualize the distribution of sales for each animal and easily identify the variations between the two months.

The sum of four consecutive integers is 134. Find the integers. (please show your work)
Answer:
Integers: 32,33,34,35
Step-by-step explanation:
Consecutive means back-to-back, with a difference of 1
Therefore this can be represented with the following equation (where x is the first number), and we can set this equal to the sum
[tex]x+(x+1)+(x+2)+(x+3)=134\\4x+6=134\\4x=128\\x=32[/tex]
Therefore since x = 32, all four integers are:
[tex]32,33,34,35[/tex]
If we check this, we can see that their sum equals to 134
[tex]32+33+34+35 = 134[/tex]

Original: $110

%Decrease:__________
Answer:
46.36%
Step-by-step explanation:
Original: 110
New: 59
Percent Decrease: x
110 - 59 = 51
51/110 ≈ 46.3636... ≈ 46.36%
-Chetan K
Answer:
46.36% or 46% (rounded)
Step-by-step explanation:
110-59=51
Question now: What percent of 110 is 51
Step 1: We make the assumption that 110 is 100% since it is our output value.
Step 2: We next represent the value we seek with x.
tep 3: From step 1, it follows that 100%= 110.
Step 4: In the same vein, x%=51.
Step 5: This gives us a pair of simple equations:
100% = 110(1)
x%=51(2)
Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS
(left hand side) of both equations have the same unit (%); we have
100%/x%=110/51
Step 7: Taking the inverse (or reciprocal) of both sides yields
x%/100%=51/110
⇒=46.36%

1. Match the polynomial with its end behavior.
A. f(x) = -2x + 3
B. f(x) = x2 - 6x + 3
1. As x gets larger and larger in either
the positive or negative direction,
f(x) gets larger and larger in the
positive direction.
C. f(x) = 1 – x2 + 2x3
D.f(x) = 7 - x4
DE
2. As x gets larger and larger in the
positive direction, f(x) gets larger
and larger in the positive direction.
As x gets larger and larger in the
negative direction, f(x) gets larger
and larger in the negative direction.
3. As x gets larger and larger in the
positive direction, f(x) gets larger
and larger in the negative (help please)direction.
As x gets larger and larger in the
negative direction, f(x) gets larger
and larger in the positive direction.
4. As x gets larger and larger in either
the positive or negative direction,
f(x) gets larger and larger in the
negative direction.
Using limit concepts, the matching pairs are:
A - 3
B - 1
C - 2
D - 4
The end behavior of a function f(x) is given by it's limit as x goes to infinity.
Function A:
[tex]f(x) = -2x + 3[/tex], then:
[tex]\lim_{x \rightarrow -\infty} f(x) = \lim_{x \rightarrow -\infty} -2x = -2(-\infty) = \infty[/tex]
[tex]\lim_{x \rightarrow \infty} f(x) \lim_{x \rightarrow -\infty} -2x = -2(\infty) = -\infty[/tex]
Thus, inverse directions, so matching pair with 3.
Function B:
[tex]f(x) = x^2 - 6x + 3[/tex], then:
[tex]\lim_{x \rightarrow -\infty} f(x) = \lim_{x \rightarrow -\infty} x^2 = (-\infty)^2 = \infty[/tex]
[tex]\lim_{x \rightarrow \infty} f(x) \lim_{x \rightarrow -\infty} x^2 = (\infty)^2 = \infty[/tex]
Always positive, so matching pair with 1.
Function C:
[tex]f(x) = 1 - x^2 + 2x^3[/tex], then:
[tex]\lim_{x \rightarrow -\infty} f(x) = \lim_{x \rightarrow -\infty} 2x^3 = 2(-\infty)^3 = -\infty[/tex]
[tex]\lim_{x \rightarrow \infty} f(x) \lim_{x \rightarrow -\infty} 2x^3 = 2(\infty)^3 = \infty[/tex]
Same directions, thus, matching pair with 2.
Function D:
[tex]f(x) = 7 - x^4[/tex], then:
[tex]\lim_{x \rightarrow -\infty} f(x) = \lim_{x \rightarrow -\infty} -x^4 = -(-\infty)^4 = -\infty[/tex]
[tex]\lim_{x \rightarrow \infty} f(x) \lim_{x \rightarrow -\infty} -x^4 = -(\infty)^4 = -\infty[/tex]
Always negative, so matching pair with 4.

Okay so for number 16
You have 2 parralel lines with a line through it.
Your trying to find the value of x
You have 2 angles given to you
one is 120 degrees whole the other is 5x+140 degrees.
They are corresponding angles. And now in this case corresponding angles are always equal.
So really all you gotta do is
120=5x+140
Now solve
-20=5x
x= -4
So the first one is x=-4
I can’t really see the other ones but here’s all you need to know
Alternate exterior - Equal
Altenrate interior - Equal
Corresponding - Equal
Interior - Not equal
Exterior-Not equal

7=3 over 4x what is x?
Answer:
x=28/3
Step-by-step explanation:
combine multiplied terms into a single fraction
7 = 3x/4
multiply all terms by the same value to eliminate fraction denominators
4 · 7 = 4 · 3x/4
cancel multiplied terms that are in the denominator
4 · 7 = 3x
multiply the numbers
28 = 3x
divide both sides of the equation by the same term
28/3 = 3x/3
simplify
a. cancel that are in numerator and denominator
28/3 = x
b. move the variable to the left
x = 28/3
Convert each fraction to its equivalent using the least common denominator.
1/3 1/4
I am, honestly, slightly confused by the question wording, so here is what I think you need! :D
We can start by listing multiplies for each:
3:
3, 6, 9, 12, 15, 18, etc
4:
4, 8, 12, 16, 20, 24, etct
We can see that the least common denominator will be 12.
Answer:
[tex]\frac{1}{3}=\frac{x}{12}=\frac{4}{12}[/tex]
[tex]\frac{1}{4} =\frac{x}{12} =\frac{3}{12}[/tex]
If you need to multiply them:
[tex]\frac{4}{12} *\frac{3}{12} = \frac{12}{144} = \frac{1}{12}[/tex]
But you do not need to use a least common denominator for multiplying and can go straight to this:
[tex]\frac{1}{3} *\frac{1}{4} =\frac{1}{12}[/tex]
Hope this helps, have a nice day!

Gordo is a fisherman. Darrin claims that Gordo over-estimates the size of his fish by 25%.
Gordo describes one fish as 40 cm long. What does Darrin claim is the length of Gordo’s
fish?
Answer:
10 cm long
Step-by-step explanation:
Darrin says that Gordo is wrong by 25% so if Gordo says his fish is 40 cm long then you just have to figure out what is 25% of 40.

what is the probability that a randomly selected day the flight will depart after 9:11 am
.135
.0235
.0015
.16
Answer
The awnser is .0235
The probability that a randomly selected day the flight will depart after 9:11 am is 0.0235. The Option B is correct.
What is the likelihood of flights departing after 9:11 am?The probability of a randomly selected day's flight departing after 9:11 am are determined by analyzing historical flight data. By examining the past departure times, we calculate the proportion of flights that departed after 9:11 am to the total number of flights.
This gives us the probability of a flight departing after that time on any given day. This probability will give us an idea of how often flights tend to depart later in the day. Therefore, the Option B is correct.
